Reading Passage

Last Friday, Mrs. Harper’s class was working on a group project about animals. Things started fine, but soon, everything got out of hand. Kids argued about who should draw the pictures. Then, Carlos tried to break the ice by making a joke. It helped a little. But Mia spilled the beans about a surprise check from the teacher.

When Mr. Simmons walked in, he cut to the chase and told everyone to calm down. “You all need to get on the same page,” he said. “No more beating around the bush.” The kids nodded.

By the end of class, they finally worked well together. They hit the nail on the head with their ideas. Mr. Simmons smiled and said, “Let’s call it a day.”

Later, Mia told her mom, “We almost missed the boat, but we made it just in the nick of time.”
